4pcs 5mm Led Red

🔹 4PCS 5mm Red LED (Diffused)

A pack of four standard 5mm red diffused Light Emitting Diodes. Perfect for status indicators, panel lights, and a wide variety of DIY electronics projects. The diffused lens provides a wide, even viewing angle and a classic red glow.

✅ Specifications:

• Color: Red

• Lens Size: 5mm (T-1 3/4)

• Lens Type: Diffused (Non-Clear)

• Forward Voltage (Vf): 1.8V – 2.2V (Typical)

• Forward Current (If): 20mA (Standard operating current)

• Maximum Forward Current: 30mA (Peak, continuous use below this)

• Luminous Intensity: Medium (Varies by bin)

• Viewing Angle: Wide (~60° – 70° due to diffused lens)

• Leg Type: Axial Leads

• Cathode Identification: Shorter lead and flat side on the lens rim

• Quantity: 4 pieces

⚙️ Features:

• Low Power & Low Voltage: Operates efficiently at common circuit voltages.

• Easy to Use: Standard axial leads for simple breadboarding, soldering, and PCB mounting.

• High Visibility: Red is a classic, highly visible color for warnings, status, and indicators.

• Diffused Light: Provides a soft, wide-angle glow without a sharp central hotspot.

• Reliable & Long-Lasting: Solid-state design ensures durability.

📦 Applications:

• Power & Status Indicators: On/Off, standby, or error indicators in electronic devices.

• DIY Electronics & Prototyping: Essential for Arduino, Raspberry Pi, and breadboard projects.

• Panel & Backlighting: Illuminating switches, instruments, and displays.

• Model & Costume Lighting: For scale models, toys, and cosplay.

• Educational Kits: Fundamental component for learning basic electronics.

🔧 Usage Guide:

1. Always Use a Current-Limiting Resistor! Connecting directly to a power source will destroy the LED.

2. Identify Polarity:

   • Cathode (-): Shorter lead. Flat side on the LED lens rim.

   • Anode (+): Longer lead.

3. Resistor Calculation: Use Ohm’s Law: R=(Vsupply−Vf)/If_R_=(_Vsupply_​−_Vf_​)/_If_​.

   • Example for 5V supply: R=(5V−2.0V)/0.020A=150Ω_R_=(5_V_−2.0_V_)/0.020_A_=150Ω. A standard 220Ω resistor is a safe, common choice.

4. Soldering: Use a low-temperature iron. Avoid prolonged heat on the leads.

⚠️ Important Notes:

• Polarity Sensitive: Will not light if installed backwards.

• Do Not Exceed Ratings: Continuous operation above 20-30mA will shorten lifespan or cause failure.

• Heat Sensitivity: Avoid excessive heat during soldering.

• ESD Protection: Handle with care.
